Definitions

  • the invention relates to a plate processing plant according to the preamble of claim 1.
  • a plate processing plant which includes a saw as a tool.
  • a saw carriage is arranged movable transversely to a feed direction of the plates to be processed.
  • a carriage is held vertically movable on which a saw blade is rotatably mounted. Due to the vertical movability of the carriage, the saw blade can be moved into and out of the feed plane of the plates.
  • a belt drive is that Saw blade connected to a drive motor, which is also attached to the carriage.
  • Object of the present invention is to provide a plate processing plant that works precisely and has a high cutting height at low height.
  • the drive motor which has a comparatively high weight, while connected to the carriage via the rocker at a fixed distance, but its weight is carried at least by means of the articulated arm of the base part.
  • the corresponding actuator which moves the carriage relative to the base part, may be smaller.
  • the movement can be done faster because the mass inertia to be overcome is lower.
  • a tilting moment acting on the carriage due to the weight of the drive motor and its mass is reduced, allowing for the use of simpler linear bearings and reducing changes in the position of the tool. This reduces costs and leads to a more precise machining result.
  • the drive motor can be arranged on a front side of the carriage, whereby the height of the tool carriage is reduced.
  • the height of a working plane of the plate processing plant can be reduced, which facilitates the operation of the system by an operator, for example, the removal and handling machined workpieces.
  • the rocker has a fastening arm which is rigidly connected to it and on which the articulated arm acts.
  • the mass of the rocker is reduced, which further enhances the advantages listed above.
  • the tool is preferably a saw blade, in the case of the corresponding plate processing installation, ie a panel dividing saw. But it is also possible that the tool comprises a milling disc or a drill.
  • the transmission element comprises a belt, preferably a toothed belt, and that the axis of rotation of a deflection roller of the belt on the carriage with the hinge axis of the rocker on the carriage is coaxial. This allows the realization of a simple, minimal weight and the tension of the belt not affecting construction.
  • the articulated arm can be arranged on the other side of the tool carriage as the rocker. This allows a reduction of the force acting on the tool carriage tilting moment.
  • the position of the hinge axis of the articulated arm on the base part is selected so that the movement of the drive motor is minimal in a movement of the carriage.
  • the influence of the mass inertia forces of the drive motor on the movement of the carriage are thereby further reduced.
  • a positioning of the joint axis of the articulated arm is particularly favorable such that upon an upward movement of the carriage, the drive motor describes a Polkurve consisting essentially of two approximately linear movements, the first movement to the outside and below and the second movement substantially horizontally and runs inwards. It is understood, however, that with other geometries, another pole curve may prove beneficial.
  • a plate processing plant carries in FIG. 1 Overall, the reference numeral 10. It comprises a support table 12 on which a stack 14 can be moved with plate-shaped workpieces in the feed direction 16 to a tool 18.
  • the latter is formed in the presently illustrated embodiment as a saw blade, with which the stack 14 can be divided with the plate-shaped workpieces in a parting plane 20.
  • the saw blade 18 is attached to a tool carriage 22, which will be referred to hereinafter as a saw carriage.
  • the tool carriage 22 can be moved parallel to the parting plane 20 in the direction of the double arrow 24, whereby it separates the stack 14 into two separate part stacks when the saw blade 18 is rotating. After the sawing movement of the tool carriage 22 this is moved back in the opposite direction, for which purpose the saw blade 18 is moved down to a position below the plane of the support table 12 so that while the rest of the stack with plate-shaped workpieces can be moved along the feed direction 16 again.
  • the saw carriage 22 initially comprises a plate-like base part 26, which by means of rollers 28 between system fixed rails (in FIG. 2 indicated by dash-dotted lines and provided with the reference numeral 30) is held in the direction of the double arrow 24 movable.
  • the movement is effected by a pinion 32, which is driven by an electric motor, not shown, and meshes with a plant-fixed toothed rail (also not shown).
  • linear guides 34 On the base part 26 is via linear guides 34 (see FIG. 3 ) a carriage 36 is held vertically movable.
  • the carriage 36 is also plate-like formed with a generally approximately square base portion 38 and a downwardly projecting from this holding portion 40.
  • the linear guides 34 comprise in a known manner two vertical and mounted on the base part 26 rails 42, each with two with the carriage 36th connected holding parts 44 cooperate.
  • the saw blade 18 is rotatably attached to an upper portion of the carriage 36.
  • a first guide roller 46 is rotatably mounted, which is connected via a first toothed belt 48 with a shaft (not numbered), on which in turn the saw blade 18 is fixed.
  • a rocker 50 is hinged on the carriage 36.
  • the latter has an S-shape and a box-like structure in plan view.
  • the belonging to the carriage 36 end of the rocker 50 is formed by a sleeve 52, the longitudinal axis 53 is coaxial with the axis of rotation of the first guide roller 46.
  • a flange 54 is formed, which is rotatably supported on the carriage 36 about the longitudinal axis of the sleeve 52.
  • the sleeve 52 is penetrated by a non-visible shaft which connects the first guide roller 46 with a second guide roller 56.
  • a drive motor 58 is fixed to this, the longitudinal axis 60 is parallel to the longitudinal axis 53.
  • a second toothed belt 64 is tensioned.
  • the saw blade 18 is thus driven by the drive motor 58 via the drive pinion 62, the second toothed belt 64, the second guide roller 56, the non-visible running in the sleeve 52 shaft, the first guide roller 46 and the first toothed belt 48.
  • the two toothed belts 48 and 64 may also be referred to as gear elements, which couple the drive motor 58 with the saw blade 18.
  • gear elements which couple the drive motor 58 with the saw blade 18.
  • the rocker 50 with the drive motor 58 is about the longitudinal axis 53rd pivotable, without thereby affecting the tension of the two toothed belts 48 and 64.
  • the rocker 50 includes a rigidly connected to its attachment arm 66. This is rigidly connected at one end to the sleeve 52 and the flange 54 and extends with its projecting end to a point above the rocker 50 and, as shown in FIG. 3 it can be seen, seen from the center of which is located somewhat further to the drive motor 58 out.
  • a spacer sleeve 68 is attached, which extends beyond an imaginary and not shown in the drawing center plane of the base member 26 away on the side facing away from the rocker arm 50 side of the base member 26.
  • the end of the spacer sleeve 68 is in turn hingedly connected to one end of an articulated arm 70, which in turn is hinged to the base member 26, on its side on which the carriage 36 and the saw blade 18 are arranged.
  • a to the spacer sleeve 68 and the end of the mounting arm 66 coaxial pivot axis is in FIG. 2 Denoted by 72, a pivot axis between the articulated arm 70 and base member 26 with 74th
  • FIG. 2 One recognizes FIG. 2 in that the drive motor 58 likewise extends beyond the center plane of the saw carriage 22 to its other side facing away from the rocker 50.
  • the S-shape of the rocker 50 is achieved that the center of gravity of the unit formed from the drive motor 58 and rocker 50 is at least approximately in the said center plane of the tool carriage 22.
  • FIG. 3 again, it can be seen that the pivot axis 72 of the articulated arm 70 on the arm 50 belonging to the mounting arm 66 between an imaginary vertical line 76, which through the center of gravity 78 of the through Rocker 50 and the drive motor 58 formed unit is, and an imaginary vertical line 80, which goes through the pivot axis 53 of the rocker 50 on the carriage 36, is located.
  • FIG. 4 is the carriage 36 with the attached saw blade 18 in its extreme lower position.
  • the articulated arm 70 is almost vertical. If now the carriage 36 is moved upwards along the linear guides 34 by means of an actuator not shown in the figures, the articulated arm 70 pivots outward about the pivot axis 74.
  • the longitudinal axis of the drive motor 60 moves along a first portion 82 of a pole curve 84 (see FIG. 4 ) to the outside and down from the in FIG. 4 in the in FIG. 5 shown location.
  • a further upward movement of the carriage 36 to the in FIG. 6 shown upper extreme position pivots the hinge arm 70 further outward until the pivot axis 72 is only slightly above the Dreh currentlytician pivot axis 53.
  • the longitudinal axis 60 of the drive motor 58 now moves substantially horizontally and inwardly along a second section 86 of the pole curve 84.
  • the pole curve 84 is extremely short, ie the movement of the drive motor 58 is minimal when the carriage 36 travels.
